WINDOW-CLEANING SEAT.

SPECIFICATION forming part of Letters Patent No. 605,610, dated June 14, 1898. I Application filed January 21,1898. Serial No. 667.390. (No model.)

To aZZ whom it may concern:

Y Be it known that we, CARL A. MiiLLER and GEORGE HINMAN, citizens of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Window-Cleaning Seats; and we hereby declare the following to be a full, clear, and exact description of the same.

Our invention relates to a removable seat or attachment for the outside of windows, which is especially useful as a support for persons cleaning the windows or performing any other work upon the outside.

It consists, essentially, in'a novel construction of the seat and a means for attaching and suspending it exterior to the window with no extensions passing into the inside; audit.

also consists in details of construction which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a sectional view of our apparatus. Fig. 2 is a view looking at it from inside the room. I

In the construction of devices forming extensions exterior to windows, and usually called window-seats, it has been customary to support such extensions by'means of arms extending inwardly across the window-sill and having hooks or other attachments which fasten to the window-frame or to some projection or portion within the room.

Our invention is designed to do away with all attachments which may extend across the window-sill to the interior and to make such attachments essentially on the outside at. the

' same time providing for greater strength and safety in the manner of support and cheapness of construction. 7

A represents a window of any description. B is the platform or extension which is to be employed outside of the window. This may.

tion of head which will prevent the slots from slipping upwardly over them. Ordinary screw-eyes, such as are here shown, make a very convenient arrangement for the purpose. These screw-eyes may be permanently left in the window-sill, and whenthe seat B is to be connected it is only necessary to hold it with the outer end inclined upwardly, so that the slotted end of the metal plate can be slipped over the shank of the screw. Then when the seat is dropped to its normal and approximately level position the upturned ends of the plate clasp the shank of the screw and project upwardly iiiside of the screw-head, so as to prevent the plates from being disengaged. In this way the inner end is very firmly locked.

In some cases it may be desired to fix the screw-eyes upon the upper surface of the window-sill, and in some cases it may be found desirable to place the screw-eyes in the outer edge, where the inner portion of the window sill is higher than the outer portion.

In-this case we have shown a hinged flap B,

which-projects over the ends of the hooks C, so that when the device is used upon the top of the window-sill this flap covers the ends and prevents their being in the way of any one at work.

The outer edge of the seat B has an upturned portion B which serves as a back for a person sitting upon it. It also serves for the attachment of screw-eyes E, in which the posts F are fitted, the lower ends of the posts entering holes made in the outer part of the seat. Across the upper ends of the posts is a transverse bar B which completes the back or formsarail to prevent the operator froxneasily slipping or falling off. This bar may-be connected with the posts by screweyes J connected with the eyes or loops at the tops of the posts and themselves screwing into the ends of the rail B The metallic'strips C, the inner which form'the hooks to engage the screweyes on the window-sill, as previously described, extend across the bottom and are toward the wall or window-jamb and'have hooks on the ends which are adapted to hook ends of IOO into screw-eyes II at such a point above the level of the seat that when the chains are thus engaged they form a strong support for the outer edge of the seat.

I I are hooks connecting with the screweyes, by which the cross-bar B is connected with the vertical standards, and these hooks, extending to the same screw-eyes with which the chains are connected, form with the chains very secure side rails to prevent the operator from falling oil the seat or support.

The whole device is easily disengaged, the use of screw-eyes for securing the parts together forming suitable connections for the suspending chains and hooks and allowing the vertical posts to be removed from the seat portion, and they and the top bar can then be folded together and the whole laid upon the seat portion and packed very closely when not in use.

Having thus described our invention, what we claim as new, and desire to secure by Let tcrs Patent, is 5 1. A wimlow-cleaning scat having metallic strips across the ends, said strips projecting interior to the inner edge of the seat and being upturned and slotted as shown, in combination with screws fixed in the window-sill and having heads with which the upturned slotted ends engage and lock.

2. A window-cleaning seat consisting of a scat-piece having transverse strips of metal across the ends, projecting beyond the interior edge and upturned and slotted, headed screws or bolts fixed in the window-seat with which said slotted bars engage and lock, chains fixed to the outer edge of the seat extending diagonally upward having hook attachments upon the upper ends and wall attaehmcnts with which they are engaged so as to support the outer edge of the seat.

3. In a window-cleaning seat, a bottom board having transverse metallic strips across the ends, said strips extending beyond the inner edge of the seat and being upturned and slotted, headed screws fixed in the windowsill with which said slotted ends engage and lock, vertical posts extending upwardly from the outer edge of the seat having a transverse barfixed across the upper ends, chains connecting with the outer edge of the seat and with attachments fixed to the outer part of the wall above the level of the seat, and hooks connecting with the top of the vertical bars at the ends of the transverse rail having the inner ends connected with the attachments upon the wall to form a support and guard.

t. In awindow-cleaningseat, abase having metal strips secured across its ends, the inner ends of said strips being turned upwardly and slotted, screw-eyes with which said inner slotted ends are adapted to engage and lock, supplemental flaps hinged to the inner edge of the seat adapted to fold down over the screw-eyes and slotted metal. ends, and suspending ehains and hooks connecting with the outer edge of the seat and connecting with attachments upon the wall above the level of the seat.

In witness whereof we have hereunto set our hands.
